The world’s oceans contain over 74,000 pieces of plastic per square mile, much of it from plastic shopping bags. Every year, over 100,000 marine creatures are found dead after getting tangled in or ingesting plastic items, and because plastic takes up to 1000 years to break down, the same item can hurt multiple animals over time.

The Great Pacific Garbage Patch — a mass of Ocean trash twice the size of Texas — was thought to be the largest garbage site on Earth, but since its discovery in 1997, five possibly larger sites have been found around the world.

In this video, Studio Swine collaborates with fishermen to show how the abundant garbage in our oceans can be transformed into something useful. Watch as they collect plastic junk during a fishing excursion and transform it into a stool (they call it a “sea chair”) without even leaving their ship. Plastic, by its very nature, can be molded into just about anything, and with Studio Swine’s open source guide, any handy person with the right resources can put a dent in marine waste.
